The study covers the biochemical composition of leaves belonging to vascular plants growing in riding bogs. Specificity is paid to the accumulation of carbon, general nitrogen, soluble and structural sugars, organic forms of nitrogen, nitrants and microcells. According to the assessment, the total nitrogen content in different species varies by more than 200 %. This regularity, it notes, is characteristic of an organic form of nitrogen. However, the content of nitrate nitrogen of different types varies slightly. The accumulation of total carbon, non-structural polysaccharide and soluble sugars also varies slightly. The ash content of mineral elements in plant leaves was also minimal; their maximum quantity was observed at a sedge spherical. Finally, the leaves of plants grown in bogs are characterized by a high accumulation of manganese and iron.
